Step 1: Select a Location

Consider the following when you select an installation location:
• Provides optimal viewing as you operate your boat.
• Allows easy access to the unit's keypad.
• Is strong enough to support the weight of the unit and protect
it from excessive vibration or shock.
• Allows room for the routing and connection of the power/data
and transducer cables. There should be at least a 3-inch (8 cm)
clearance behind the case.
DO NOT mount the unit in an area that is exposed to extreme
temperature or conditions.
NOTE: The temperature range for the unit is 5°F to 131°F
(-15°C to 55°C). Extended exposure to temperatures exceeding
this range (in storage or operating conditions) may cause failure
of the LCD screen. This type of failure and related consequences
are NOT covered by the manufacturer's limited warranty.
NOTE: References to a transducer in this section apply only to
units with an 's' suffix (i.e., 440s). These units use the transducer
as part of the sonar feature. If you do not have an 's' unit, then
disregard instructions regarding installing a transducer.
